Exact-match DDR5 kit for Supermicro H13SST-GC

This 192GB kit delivers four 48GB DDR5-4800 RDIMMs built to the Supermicro H13SST-GC motherboard's memory-population rules. Registered ECC modules operate at 1.1V with CL40 timing so the controller recognises full capacity at rated speed. It is not for systems that require UDIMM or SODIMM form factors.

Registered architecture under sustained load

Registered buffering offloads the memory controller when all four slots are populated, allowing each DIMM to run at its rated 4800 MT/s without throttling. ECC corrects single-bit errors on the fly to prevent silent data corruption during long compute runs. Buyers who need higher frequencies or lower latencies than CL40 will not find them here.

288-pin RDIMM build and daily implications

Modules use major OEM Samsung, Micron or Hynix chips without heat spreaders, relying on server chassis airflow for cooling. The 288-pin Registered form factor fits only boards wired for RDIMMs. Installers must follow the motherboard manual for approved population order to avoid boot failure.

Questions about this item

How much heat should I expect from the 1.1 V DDR5 4800 RDIMMs when the Supermicro H13SST-GC runs all day?

Each 48 GB module operates at 1.10 V without a heat spreader, so sustained load relies on chassis airflow to keep temperatures within DDR5 limits.

What must my Supermicro H13SST-GC already have to accept this 192 GB kit?

The board needs four free 288-pin DDR5 RDIMM slots that support 2Rx8 registered ECC modules and a memory controller rated for DDR5 4800 at 1.1 V.

Will the CL40 2Rx8 registered ECC timings work with older DDR5 modules I might keep installed?

Mixing different ranks, latencies or voltages is not recommended; the board will downclock all DIMMs to the slowest common settings, reducing performance.
